Question

If 180°<θ<270°, and sin⁡θ=−3/4, what is the value of sin(−θ)?

Answer 1

Answer:

$sin(-\theta)=\frac{3}{4}$

Step-by-step explanation:

Given:

180°<θ<270° and $sin(\theta)=-\frac{3}{4}$

We know for any angle $\theta$,

$sin(-\theta)=-sin(\theta)$

∴$sin(-\theta)=-(-\frac{3}{4})=\frac{3}{4}$
